Heat recovery is often described as “sensible” or “enthalpy.” The difference decides comfort, energy savings, and which technology to specify. Sensible Recovery Transfers temperature only. Plate exchangers, heat pipes, and run-around coils are sensible devices. They pre-heat or pre-cool the supply air without adding or removing moisture. Enthalpy Recovery Transfers both temperature and moisture. Enthalpy […]
Enthalpy vs Sensible Wheel: Moisture Transfer
A rotary energy wheel is one of the most effective air-to-air recovery devices available, routinely reaching 70 to 85 percent total effectiveness, but not every application wants what the wheel is selling. The deciding factor is the matrix coating: a plain aluminium wheel moves only sensible temperature energy, while a desiccant-coated enthalpy wheel also transfers […]
